There could be a multitude of reasons: * maybe you got an instant stutterfree flow of words because you didn't perceive stutter triggers * Maybe you didn't justify or anticipate stopping articulators * Maybe you didn't choose or weren't convinced to stop articulators * Maybe you did (negatively or positively) evaluate stuttering but the fear, true intentions and belief 'stutter' will happen was not 'real' enough * Maybe you created a new condition like "It's time for more fluency, but only in this specific time and situation" So the question is then, what do you (experience) or think is what happened?
